Unused Dice

I'm feeling very remorseful at the moment. I was cleaning out a shelf in the basement and I ran across this box of Chessex dice. I suspect its not really something I'm suppose to have. Its a retailer reference pack that has one six sided die in each color that was available at that time. I'm guessing this has to be at least 10 years old. I'll be breaking this bad boy out for the next game requiring D6s.
